Moral foundations tracked over 200 years of lexicographic data, and their predictors

The prediction that reduction of negative selection decreases group-level competitiveness, as reflected in increased individual-focused and diminished group-focused moral foundations, is tested. To measure this hypothesized shift in moral foundations, we conduct a culturomic analysis of the utilization frequencies of items sourced from the moral foundations item pool, tracked among Britannic populations from 1800 to 1999 using Google Ngram Viewer. The resultant higher-order factor, which tracks increasing individualizing values and decreasing binding values, is termed Asabiyyah (capturing social cohesion and collective purpose). Two predictors of this factor are examined: change in the strength of intergroup competition and change in levels of indicators of developmental instability. Both the strength of intergroup competition and levels of developmental instability associate with Asabiyyah. Rising developmental instability mediates the impact of inter-group competition, indicating that reduced between-group competition might have relaxed negative selection against mutations, which might reduce Asabiyyah via their effects on inter-genomic transactions. These results must be interpreted carefully, given the clear real-world evidence that explicit commitment to group-oriented values often features in harmful and maladaptive social and political ideologies of an extreme character.

Spare the rod and spoil the group's cultural fitness? Conditions under which corporal punishment leads to detrimental and beneficial outcomes

Corporal punishment of children is common across human history, and the specific practice of striking the buttocks, known as spanking, seems to have developed independently across a number of separate cultures. This pattern suggests adaptive value, posing a paradox in view of the many reviews stating that spanking has purely negative outcomes on future mental health, and the recommendation of the American Academy of Pediatrics that it be outlawed. We purport to resolve this paradox by separating this particular type of corporal punishment from less controlled lashing out in anger, and we reanalyze these reviews in terms of psychological and physical health outcomes. We find that spanking is associated with positive mental health outcomes when (1) performed by calm parents in a (2) ritualized, structured fashion and combined with (3) other disciplinary techniques within (4) a loving relationship with the child, typically (5) as part of the practice of moral, collective religiosity, and when (6) controlling for confounding variables. In that spanking is noticeably practiced by conservative religious cultural groups, we hypothesize that it can be a fitness-promoting form of behaviour in line with religiousness being an example of a group-fitness-promoting adaptation.
